Product Name: CA28-5SB High-Efficiency Coalescing Filter Element (Stainless Steel, 5-Inch)

1. Product Concept

The CA28-5SB is a premium, corrosion-resistant coalescing filter cartridge engineered to deliver uncompromising performance and durability in demanding industrial environments. It combines the robust filtration capacity of the standard 5-inch CA28 series with the critical upgrade of stainless steel ("SB") construction for all wetted structural components. This product is designed to address the dual challenges of achieving high-purity fluid separation and withstanding corrosive, humid, or otherwise aggressive operating conditions. It serves as a reliable guardian for compressed air and process gas systems, ensuring long-term protection of sensitive downstream equipment where material failure is not an option.

2. Key Features & Advantages

• Superior Corrosion Resistance & Durability

• Constructed with stainless steel (e.g., 304/316 grade) end caps and an internal support core, providing exceptional resistance to rust, oxidation, and chemical attack. This fundamentally eliminates a common failure mode in harsh environments, significantly extending service life and reliability.

• High-Efficiency Coalescing Performance

• Utilizes an advanced multi-layer glass fiber or synthetic media pack designed for efficient liquid and solid contaminant removal, typically rated for particles and aerosols ≥0.01 µm.

• Capable of maintaining ultra-low residual oil content, often ≤0.01 ppm, ensuring the highest level of output fluid purity.

• Robust Design for Demanding Service

• Engineered to handle higher operating pressures (up to 16 bar) and a wider temperature range compared to many standard filters, offering greater application flexibility.

• The stainless steel construction also allows for potential clean-in-place (CIP) procedures or use in applications with stringent hygienic requirements.

• Seamless Premium Upgrade

• Maintains the universal 5-inch (127 mm) physical dimensions and standard M30×1.5 male thread interface, making it a direct, drop-in replacement for standard CA28-5 cartridges, but with significantly enhanced material longevity.

3. Primary Application Areas

• Corrosive and Marine Environments: Offshore platforms, ships, coastal facilities, and chemical processing plants where saltwater atmosphere or chemical fumes are present.

• Critical High-Purity Industries: Pharmaceutical and biotechnology process gases, food and beverage compressed air (with appropriate validations), and semiconductor manufacturing support systems where material integrity and purity are paramount.

• Breathable Air and Medical Gas Systems: Hospital central air systems, breathing air compressors for safety applications, where filter material safety and reliability are critical.

• General Industrial Premium Applications: Any compressed air or gas system in demanding conditions where upgrading to stainless steel components is a cost-effective strategy to prevent downtime, reduce maintenance, and protect capital investment.
